节点选用和数据出来列出详细步骤。
题目一：用软件KNIME，使用全球恐怖主义数据库（GTD）数据集，制作一份世界地图可视化，其中各国根据该国记录的事件总数进行颜色编码。 可视化应清晰展示各国事件的强度，使用适当的颜色标尺和图例。本活动的重点在于按国家汇总数据（无需使用单个事件的地理坐标）。

题目二：第二个问题：使用全球恐怖主义数据库（GTD）的数据集，制作一个堆叠条形图（stacked bar chart），展示各大陆每年发生的事件数量。
每个柱应对应一年，每个柱内堆叠的类别应代表各大洲。图表应能直观展示事件随时间的演变以及各大陆在各时期的相对参与度。
提交：生成一张可视化图像，格式为 PNG、JPG 或 SVG。

Detailed steps for node selection and data generation.
Question 1: Using KNIME, create a world map visualization using the Global Terrorism Database (GTD) dataset, color-coding each country based on the total number of incidents recorded. The visualization should clearly demonstrate the intensity of incidents in each country, using an appropriate color scale and legend. This activity focuses on aggregating data by country (no need to use the geographic coordinates of individual incidents).

Question 2: Second question: Using the Global Terrorism Database (GTD) dataset, create a stacked bar chart showing the number of incidents per continent per year.
Each bar should correspond to a year, and the stacked categories within each bar should represent each continent. The chart should visually demonstrate the evolution of incidents over time and the relative involvement of each continent over time.
Submission: Generate a visualization image in PNG, JPG, or SVG format.
